It's on my todo list to upgrade to top of Linus's tree, but perhaps this is a useful data point. The reported corruptions are with a .37 forward port someone did of my parallel kcryptd patch. The 2.6.36 (and earlier) versions are rock solid with many users. The classic dmcrypt is single threaded and very slow. > As another thought, what version of GCC are people using who are having difficulty? Could this perhaps be a compiler-related issue? A compiler problem seems very unlikely here. What may be an useful experiment would be to test 2.6.37-rc + ext4 over device mapper, but not dmcrypt. If that fails too then it's likely some generic device mapper problem. -Andi -- ak@...ux.intel.com -- Speaking for myself only. -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
